摘要

Alongside electronic components for transacting mobile networked communications and service control there are one or more first components (2) in a mobile telephone (1) for determining physical distance between the mobile telephone and external objects or appliances (3). These first components exchange data with second components to measure distances. Relying on the distance determined by the first component can control functions in the second components.
